Hello Friend. If the yoke is short, replace it with another one of the same number or if you can repair it, you have to disassemble all the winding there where the short is either of the horizontal bovines or the vertical vobinas. but if you find another yoke equal to that it is better but then you solve the fault.

friend. first the measurement of the horizontal bovines and the vertical vobinas that measure equal to that yoke that you have bad and the most practical that is of the same number as the one that you have repaired

friend. because if the one you find measures well in both bovines it may not fit well in the neck of the tube so it is better according to the number of the yoke
